One evening, a friend was in a rush to catch the train home. They ran through the station, barely making it onto the train just as the doors closed. Feeling relieved, they sat down and relaxed, only to realize halfway through the journey that they were on the wrong train, heading in the opposite direction. With no choice but to ride it out, they ended up at a station an hour away from their destination. Eventually, they made it home, but not without a long, unintended detour that turned their usual 30-minute trip into a 3-hour adventure.
